- jax.numpy.rollaxis(a, axis, start=0)[source]#
Roll the specified axis backwards, until it lies in a given position.
LAX-backend implementation of
The JAX version of this function may in some cases return a copy rather than a view of the input.
Original docstring below.
This function continues to be supported for backward compatibility, but you should prefer moveaxis. The moveaxis function was added in NumPy 1.11.
a (ndarray) – Input array.
axis (int) – The axis to be rolled. The positions of the other axes do not change relative to one another.
start (int, optional) –
start <= axis, the axis is rolled back until it lies in this position. When
start > axis, the axis is rolled until it lies before this position. The default, 0, results in a “complete” roll. The following table describes how negative values of
arr.ndim + 1
res – For NumPy >= 1.10.0 a view of a is always returned. For earlier NumPy versions a view of a is returned only if the order of the axes is changed, otherwise the input array is returned.
